Mounting arrangement for glass doors

ABSTRACT

A mounting arrangement for glass doors includes an upper mounting having a mounting body with a clamping device for the glass leaf and a displaceable bearing pin for engaging in a counterbearing at a transom and a lower mounting with a mounting body with a clamping device for the glass leaf, and with a receiving recess for a floor door closer or a floor bearing. The two mounting bodies are arranged parallel to the vertical axis (H) of the glass leaf, and each clamping device is provided with longitudinally extending grooves for receiving fastening screws which project through screw holes in the clamping device and bore holes in the glass leaf. A clamping insert is provided for inserting into the grooves and has a recess for a cover panel. The mounting body and the counterbearing can be covered by means of covers, wherein the cover is provided with elongated holes which extend under the clamping insert and cover panel. Lift-out protection is provided in the upper mounting for the all-glass leaf in the closed position.

The invention is directed to a mounting arrangement for glass doorscomprising an upper mounting or mounting having a mounting body with aclamping device for the glass leaf and comprising a displaceable bearingpin for engaging in a counterbearing at the transom or the like andcomprising a lower mounting with a mounting body with a clamping devicefor the glass leaf, and with a receiving recess for a floor closer or afloor bearing.

Mounting arrangements have been known for a long time. However, themountings and the upper counterbearing which is supported at anoverpanel or transom above the glass leaf of the glass door aregenerally oriented transverse to the vertical axis of the glass door.This spoils the overall visual effect because the substantially verticaloverall orientation of the glass door is interrupted by transverselyextending elements and is perceived by the observer as unattractive.Further, a side part located next to the glass door is oftenincorporated in the counterbearing resulting in a somewhat clumsyoverall appearance.

Further, as a result of this design, a gap can form between the frontedge of the side part and the front edge of the glass leaf facing theside part when the glass leaf is swiveled, so that the user can bepinched in this gap causing painful injuries.

DE 93 07 027 U1 is directed to an all-glass installation whichessentially comprises a glass door and laterally adjoining wallelements, which are likewise made of glass, and a transom located abovethe door. A mounting whose lower and upper strip are not constructed inthe conventional horizontal form, but rather are installed vertically,is used in this all-glass door. This makes it possible to place thedevice necessary for supporting the door so far out at the edge of thepane of glass that only a semi-circular bore hole is needed in the lowerand upper area of the all-glass leaf, as well as the bore holes, locatedabove, which are needed for fastening of mounting generally. Theinterconnection of glass elements is ensured by means of a connectionelement which requires only one centering bore hole and which can bemounted without great effort. The connection elements are designed insuch a way that one half of the element is inserted into the bore holeof the glass plate from each side and these halves are joined by aconnection element. The present invention proceeds from this genericprior art.

EP 0 608 063 A2 shows a glass door which is embedded by means of acircumferentially extending frame. There are corresponding horizontalmounting parts inside the frame for operative connection of theall-glass door to a lower and upper bearing.

DE 298 13 219 U1 discloses a mounting for an all-glass leaf which iscrowned by caps. Different inserts can be inserted into the caps as anartistic possibility for aesthetic, visual purposes.

DE 299 24 319 U1 discloses a mounting system for the rotatable bearingsupport of a door leaf at a frame structure. A mounting of this kindcomprises two mounting parts which are formed by an intermediate spaceextending longitudinally. The door leaf is clamped in between themounting parts. Depending on function and use, the mounting parts areeither connected by a web so as to form one piece or are formedcompletely separately. The mounting parts are fastened to one anotherfrom one side by corresponding screw elements.

Therefore, it is the object of the present invention to provide amounting arrangement which achieves a visual/aesthetic effect and whichis adapted to the overall arrangement of the glass door in a slender,delicate and unobtrusive manner.

This object is met through the features indicated in patent claims 1 and2. Advantageous embodiments of the subject matter of the inventionfollow from the subclaims.

By means of the mounting arrangements indicated in patent claims 1 and2, the mounting arrangements are not visually obtrusive because they arefully integrated into the door. They are inconspicuous because thevertical orientation of the glass door is not interrupted bytransversely extending elements and fits in with the overall arrangementin a slender and delicate manner.

A stationary side part which is preferably made of glass is arrangedadjacent to the glass leaf and the transom; the upper mounting and thelower mounting and the counterbearing do not engage with the side part.In particular, this step underlines the unobtrusive, slender anddelicate effect of the mounting arrangement according to the inventionbecause the glass door is not fastened to the side part.

According to an advantageous further development, the glass leaf isprovided at the top and bottom with a vertically extending glass cutoutfor receiving the upper mounting or lower mounting or a clamping devicethereof. In addition, preferably two bore holes located one above theother vertically adjoining each glass cutout are provided for fasteningto the clamping device. In this way, the upper or lower mounting or theclamping devices thereof can be fastened securely to the glass door onone hand and the delicate construction of the mounting/door unit can besupported in this way on the other hand.

In order to ensure a good mutual support between the glass leaf andclamping device according to an advantageous construction, every glasscutout has a diagonally extending contact edge which makes contact at aninclined surface provided in the clamping device.

The clamping device has a receptacle for the glass cutout with twooppositely located clamping surfaces for lateral contact at the glassleaf. Due to this construction, an effective transmission of force and asecure connection between the mounting and door can be achieved.

In order to avoid obtrusive fastening devices for fastening the clampingdevices to the glass leaf, the clamping device is provided withlongitudinally extending grooves for receiving fastening screws whichpenetrate through screw holes in the clamping device and the bore holesin the glass leaf.

A clamping insert is preferably provided for inserting into the channelsin order to reinforce the channels and to ensure a bearing support ofthe fastening screws which is robust and free of play even over a longerperiod of use.

According to an advantageous further development, the clamping insert isprovided with a receptacle for a cover panel. This not only has apositive influence on the overall visual appearance of the mountingarrangement, but also makes it possible to adapt to different colors,shapes, etc.

Visual adaptation of the mounting arrangement according to the inventioncan be further improved according to a preferred embodiment form whenthe mounting body and the counterbearing can be covered by a cover.

According to the construction indicated in patent claim 1, the coverpreferably comprises tubular pieces which can slide over the mountingbody and counterbearing.

According to one embodiment form, only the mounting body and thecounterbearing are covered by the tube. According to an alternativeconstruction, however, the tube can also extend over the entire heightof the glass leaf. This construction serves at the same time to protectagainst pinching because pinching between the side part and the glassleaf can be reliably prevented by reducing the existing gap.

Further, the mounting arrangement according to the invention is notvisually obtrusive because it emphasizes the vertical orientation of theglass door due to its slender, delicate shape. Further, the cover offersgreat leeway for architectonic and design variants. According to anadvantageous further development, the tube is provided with alongitudinal slot and covers the back edge of the glass leaf so that thetube fits well visually into the overall impression of the door.

When the tubular cover extends over the entire height of the glass leaf,another mounting part is provided to increase stability and to clamp thetube at the glass leaf, preferably in the middle area of the back edgeof the glass leaf. This mounting part can be constructed in a mannersimilar to the upper and lower mounting. According to an advantageousfurther development, bore holes are provided in the glass leaf forfastening this mounting part.

The covers can be provided in different colors and/or shapes, e.g.,round, semi-circular, angular, oval, etc., in order to adapt easily toany design variants.

In an advantageous further development, the cover is provided withelongated holes which extend under the clamping insert and cover panelso that the cover does not hinder fastening of the mountings or, inparticular, the accessibility of the fastening screws. Therefore, thecover panel of the clamping insert can easily be removed when it isnecessary to access the fastening screws.

The upper and lower mounting are preferably covered at their outwardlyfacing front side with a cover cap which is preferably made of plastic.

The bearing pin is advantageously supported in the upper clamping deviceso as to be displaceable in axial direction of this clamping device sothat the glass leaf can be mounted simply and easily. In this way, thebearing pin can be conveniently inserted into the upper counterbearing.

In the mounting arrangement indicated in claim 15, the upper mounting isprovided with lift-out protection. The lift-out protection is outwardlyinconspicuous because it is arranged beneath the mounting body that iscrowned by cover caps or beneath a clamping device.

According to an advantageous further development, the bearing pin isfastened to the mounting body and/or to the clamping device for theall-glass leaf by means of at least one fastening screw. The fasteningscrew penetrates into and extends through the bearing pin orthogonal tothe center axis of the bearing pin. The fastening screw is inserted intoan elongated hole inside the mounting body and/or clamping device insuch a way that the bearing pin is displaceable in direction of thevertical axis. The thread of the fastening screw penetrates into athreaded bore hole inside the bearing pin. By tightening the fasteningscrew when the bearing pin is extended, the latter is connected in africtional and positive engagement to the mounting body and/or theclamping device.

Owing to the fact that the bearing pin is located inside a pocket hole,it is possible to introduce another screw element below the extendedbearing pin, which other screw element likewise penetrates the mountingbody and/or the clamping device orthogonal to the center axis of thebearing pin. Owing to the arrangement of the securing screw, namely atan offset of 180° to the fastening screw, it is not possible todisassemble the installed all-glass leaf when the door is closed. Thiscan only be carried out when the securing screw on one side of theall-glass door and the fastening screw on the opposite side areunscrewed or loosened. However, this means that the mounting and/or theclamping device must be accessible from both sides of the door leaf.

If only the securing screw is removed after the covering has beenremoved on one side of the all-glass door, the bearing pin cannot belowered due to the design because the fastening screw holds the bearingpin in its position even when the securing screw is removed. This is dueto the fact that the fastening screw, which is offset by 180° relativeto the securing screw, is accessible in this case within the space. Thefastening screw can likewise be loosened and the bearing pin canaccordingly penetrate into the mounting body and/or the clamping deviceonly after opening the all-glass door. However, this can only beaccomplished when the securing screw has been completely removed. Whenthe securing screw is removed, the lower part of the pocket hole intowhich the bearing pin penetrates is cleared.

In another instance, if a person loosened only the fastening screw, thebearing pin could not penetrate down into the pocket hole because of thesecuring screw which is screwed in on the opposite side.

It is clear that an arrangement of the securing screw and fasteningscrew of the bearing pin such as is described above results in a simplebut effective securing of the bearing pin. The step of providing asecuring screw does not impair adjustability when inserting the glassdoor. The design of the mounting is not important.

The details of a mounting arrangement 1 according to the invention areshown in the drawings. A glass door 2 is shown only insofar as itpertains to the description of the invention.

FIG. 1 shows the glass door 2 only in the area of the mountingarrangement 1 according to the invention. The glass door 2 comprises aswivelable glass leaf 6, an overpanel or transom 9 which is arrangedabove the glass leaf 6 and which is preferably made of glass, and a sidepart 15 which is arranged next to the glass leaf 6 and transom 9 andwhich is likewise made of glass.

The glass leaf 6 is held exclusively in the transom or in the floor bymeans of the mounting arrangement 1 according to the invention. For thispurpose, the mounting arrangement 1 comprises an upper mounting 3 and alower mounting 10.

The upper mounting 3 has a mounting body 4 with a clamping device 5..The clamping device 5 has a bearing pin 7 which projects upward in theinstalled position and which can engage in a corresponding bearingopening in a counterbearing 8 which is fastened to the transom 9.

The lower mounting 10 likewise has a mounting body 1 with a clampingdevice 5′. The clamping device 5′ has a receiving recess 12 for a floorcloser 13 or a floor bearing 14 at a surface that faces downward in theinstalled position.

The arrangement and orientation of the lower mounting 10 and of theupper mounting 3 are carried out in such a way that the two mountingbodies 4, 11 are oriented parallel to a vertical axis H of the glassleaf 6. The counterbearing 8 is also preferably constructed like themounting body 4, 11 and is arranged parallel to the vertical axis H ofthe glass leaf 6.

In order to ensure a secure fastening of the clamping device 5, 5′ tothe glass leaf 6, the glass leaf 6 is provided in its lower area with aglass cutout 16 which is so arranged that a cutout is open toward theside and toward the bottom (see FIG. 2). This glass cutout 16 passesover an inclined contact edge 19 into a side edge of the glass leaf 6.Two bore holes 18 arranged one behind the other vertically are arrangedadjoining this glass recess 16.

Similarly, the glass leaf 6 is provided in its upper area with a glasscutout 17 which is arranged in such a way that there is a cutout whichis open toward the side and toward the bottom (see FIG. 2). This glasscutout 17 likewise passes from an inclined contact edge 19 into a sideedge of the glass leaf 6. Two bore holes 18 situated one behind theother vertically are arranged adjoining this glass recess 16 in thiscase also.

An upper or lower mounting 3, 10 of the mounting arrangement 1 accordingto the invention is shown in detail in FIG. 3. The upper or lowermounting 3, 10 is provided with a clamping device 5, 5′ by means ofwhich they can be fastened to the glass leaf 6.

The clamping device 5, 5′ has a receptacle 21 with two lateral clampingsurfaces 20 which contact the side surfaces of the glass leaf 6 in theinstalled state. The receptacle 21 is defined on one side by an inclinedsurface 22 which is contacted by the contact edge 19 of the glass leaf 6in the installed state. Further, channels 23 which extend inlongitudinal direction and in which screw holes 24 are located areprovided in the side surfaces of the clamping device 5, 5′ which faceoutward. Fastening elements, not shown, can be inserted into these screwholes 24. These fastening elements penetrate the screw holes 24 in theclamping device 5, 5′ and the bore hole 18 in the glass leaf 6 in theinstalled state and accordingly hold the clamping devices 5, 5′ securelyand exactly in position at the glass leaf 6. In order to ensure a goodcontact of the clamping surfaces 20 at the glass leaf 6, the clampingdevice 5, 5′ is provided with a slot 27 on its side facing away from theglass leaf 6.

The glass leaf 6 is held in the clamping device 5, 5′ exclusively byclamping action. The fastening elements projecting through the screwholes 24 serve only to generate a clamping action between the clampingsurfaces 20, but not to support the glass leaf 6.

A clamping insert 25 which penetrates the screw holes 24 can be insertedinto a channel 23 for reinforcement. This clamping insert 25 in turn canbe provided with a groove for receiving a cover panel 26 (See FIGS. 10to 12).

The upper mounting 3 is shown in FIG. 4. The bearing pin 7 whichprojects upward out of the mounting 3 serves to engage with thecounterbearing 8. The bearing pin 7 is mounted so as to be displaceablein longitudinal direction of the mounting 3 so that the glass leaf 6 canbe easily installed or, if necessary, also removed again. An adjustingscrew 28, for example, is provided for this purpose. This adjustingscrew 28 is arranged in the channel 23, is displaceable in an elongatedhole 29 and is connected to the bearing pin 7 in a manner not shown inmore detail. When the adjusting screw 28 is loosened, it can movedownward in the elongated hole 29 out of the position shown in FIG. 4and carries the bearing pin 7 along with it so that the latterdisengages from the counterbearing 8. Conversely, when the adjustingscrew 28 is moved upward in the elongated hole 29, the bearing pin 7exits upward out of the mounting 3 and can engage with thecounterbearing 8.

Two variants for supporting the lower mounting 10 are shown in FIGS. 7to 9. Either a floor closer 13, according to FIG. 8, or a pin of a floorbearing 14 can engage in the receiving bore hole 12 provided in thelower mounting 10.

An optional adapter 31 for an alternative floor bearing of the lowermounting 10 is shown in FIGS. 14 to 16. The lower mounting 10 has theshape shown in FIG. 13 with a hexagon opening 30. The adapter 31 shownin FIGS. 14 to 16 can be inserted into this hexagon opening 30.

The adapter 31 has a connection plate 32 from which a hexagon 33 extendsupward, this hexagon 33 serving to engage with the hexagon opening 30 inthe lower mounting 10. A receptacle 34 in which the floor closer 13 canengage is provided in the connection plate 32. Further, a notch 35 isprovided in the connection plate 32 for adjustment and orientation.

The mounting arrangement 1 according to the invention is provided withadditional covers 38. For this purpose, recesses 35 into which thecovers 38 can be inserted can be arranged in the mountings 3, 10. Thecover 38 can only extend over the mounting bodies 4, 11 and thecounterbearing 8 or can extend over the entire height of the glass leaf6. The covers 38 can have different shapes, e.g., round or angular,and/or different colors and, for example, can be made from tubes whichare slid over the mountings 3, 10 and the counterbearing 8. The tubethat is used as a cover 38 can be provided with a longitudinal slit inthe shape of a cutout 46 and can cover the rear edge of the glass leaf6. When the tube 38 extends over the entire height of the glass leaf 6,another mounting part, not shown, can be provided for clamping the tube38 at the glass leaf 6, preferably in the center area of the rear edge.This mounting part which can be constructed similar to the upper orlower mounting 3, 10 can be fastened in the glass leaf 6 by means ofbore holes.

The cover 38 is provided with lateral elongated holes which extend underthe clamping insert and cover panel. Further, the upper or lowermounting 3, 10 can be covered by a cover cap 39, preferably made ofplastic, at its front side facing outward.

The mounting arrangement 1 according to the invention can be used insingle-leaf or two-leaf glass doors.

The mounting 3, 4 is connected to the glass leaf 2 by means ofconnection elements. For this purpose, longitudinal grooves in the formof recesses 21 can be provided in the mounting 3, 4 and clamping insertscan be inserted into these recesses 21 to improve the bearing support ofthe connection elements. The clamping inserts are covered externally bycover panels 38.

In order to ensure easy access to the connection elements, the covers 38are provided with elongated holes 43 which extend under the clampinginsert 25 and its cover panel 26, 37 (see FIG. 17). The cover 38 isfixed to the mounting 3, 10 in this way. In addition, the front sides ofthe mountings 3, 10 which face outward are provided with a cover cap 39.

Different constructions can be realized by means of the mountingarrangement 1 described above with the upper mounting 3 and the lowermounting 10. One such construction is that described above in which theupper mounting 3 with the mounting bodies 4 is used as both uppermounting 3 and lower mounting 10, corresponding bearing pins 7 oradapters 31 being used in each instance to adapt to the surroundings.The bearing pin 7 and the adapter 31 are also provided in the mountingarrangement 1 when only the upper mounting 3 and the lower mounting 10are not crowned by short covers 38 but, instead, when a continuous cover38 is used over the entire vertical axis H of the glass door 2 from thetop to the bottom in order to realize simultaneously a correspondingprotective clamping protection relative to the secondary closing edge.

FIG. 24 shows a continuous cover 38 of this kind in which the elongatedholes in the form of openings 43 for the clamping inserts andaccordingly for fastening the cover 38 to the mounting body 4 locatedunder the latter can be realized in the form of clamping devices 5 and5′. The opening 43 is surrounded on all sides by material so that thetermination 45 is rounded for purposes of adapting in an attractivemanner to the aesthetic attributes of the mounting. A cutout 46 extendsover the entire length of the cover 38 according to FIG. 10, i.e., overthe lower mounting 10 as well as over the upper mounting 3, in order toensure that the glass door 2 penetrates into the tube 38. A border 44forms the lower and upper termination of the cover 38. Projections 42are formed inside the cover 38 in order to prevent rotation of the cover38 on the mounting bodies 4 or clamping device 5, 5′.

A cover 38 which is used only for an upper mounting 3 or a lowermounting 10 or a counterbearing 8 can be seen in FIG. 20. Thecorresponding opening 43 and the projections 42 are both provided. Thiscover 38 is likewise fastened by means of clamping inserts 25, so thatno fasteners are visible at the cover 38.

An overall view of a mounted lower mounting 10 is shown in FIG. 17 forpurposes of illustration. The glass door 2 is not shown for the sake ofclarity. The cover 38 crowns the mounting with the clamping device 5, 5′and the adapter 31. The clamping inserts 25 which will be described inmore detail and in which a covering 37 in the form of a plastic coveringis inserted form the outer termination.

It is clear from FIG. 18 that the cover 38 is slid over the lowermounting 10. The projections 42 engage in grooves 36 of the lowermounting 10 in order to prevent the cover 38 from rotating relative tothe lower mounting 10. Further, it is clear that the channels 23 and thescrew holes 24 are covered by the cover 38.

An exploded view of the lower mounting 10 in FIG. 19 makes clear onceagain how the cover 38 is fastened to the mounting body after themounting body or clamping device 5, 5′ is crowned without any fasteningmeans being outwardly visible.

Cover caps 39 form the upper termination of the mounting according toFIG. 19, a projection 40 that is inserted in the channels 23 beingformed at each cover cap 39. The caps 39 are preferably made of anappropriate plastic.

The cover 38 is connected indirectly to the clamping device 5, 5′ in thedirection of the vertical axis H of the mounting arrangement 1 bycorresponding screw elements.

As is shown in FIGS. 22 to 24, there is a wide variety of bore holes oropenings, e.g., in the shape of an elongated hole 47, inside theclamping inserts 25. In addition to countersink bore holes 56, there arefastening bore holes 57, threaded bore holes 58 and through-holes 59 and60 at different locations in order to realize a universal applicabilityof the clamping insert 25 with short covers 38 for the upper mounting 3and lower mounting 10 and for the counterbearing 8, respectively, aswell as with a device for actuating a door of this type withoutclamping, in which case the cover 38 extends over the entire verticalaxis H of the glass door 2. The clamping insert 25 is closed toward theoutside by corresponding coverings 37 or cover panels 26. Projections 41which snap into the corresponding bore holes 57 located underneath themare formed at the coverings 37 in order to achieve an invisiblefastening between the covering 37 and the clamping insert 25.

FIG. 21 shows an upper mounting 3 which is used for all-glass doors 2with a glass leaf.

The upper mounting 3 substantially comprises the mounting body 4 havingthe glass receptacle 21 for the glass leaf 2 of the all-glass door. Apocket hole 53 is located in the upper area of the mounting body 4, thedisplaceable bearing pin 7 of an upper bearing, e.g., in the transom 9or the like, penetrating into this pocket hole 53. The mounting body 4is defined laterally by the clamping inserts 25 (clamping plates). Theclamping inserts 25 are covered in turn by cover panels 26, 37 andfitted over the fastening bore holes 57. When the cover panels 26, 37are removed, two screw elements, namely, a holding screw 50 and asecuring screw 48, are accessible inside the upper mounting 3. Theholding screw 50 is embedded by its head inside an elongated hole 47oriented in axial direction and penetrates with its thread into aninternal thread 51 located in the bearing pin 7. When the bearing pin 7is moved out (see FIG. 21), the holding screw 50 is tightened so that africtional and positive connection is formed between the bearing pin 7and the upper mounting 3.

Directly below the end of the bearing pin 7 which penetrates into thepocket hole 53, the securing screw 48 extends orthogonal to thelongitudinal axis of the mounting. The securing screw 48 accordinglypenetrates the pocket hole 53. The length of the securing screw 48 isadapted to the thickness of the mounting body 4 or of the clampinginserts 5, 5′. However, the securing screw 48 is arranged at an offsetof 180° to the holding screw 50. This means that, e.g., the securingscrew 48 lies outside the space and the holding screw 50 is locatedinside the space when the door leaf is closed. Accordingly, when thedoor is closed, no one can unscrew both screws, namely, the securingscrew 48 and the holding screw 50, simultaneously in order to lower thebearing pin 7 into the pocket hole 53 and then remove the door leaf fromits operational position.

If the securing screw 48 which is screwed into an internal thread 55 ofthe clamping insert 25 were removed, it becomes clear that loosening theholding screw 50 can cause the bearing pin 7 to be lowered only if thesecuring screw 48 is removed beforehand.

This situation, namely, the removal of the holding screw 50 from thebearing pin 7 while the securing screw 48 is inserted in the thread 55at the same time, does not allow the bearing pin 7 to be lowered.

As is clear from the embodiment example shown in FIG. 21, in contrast tothe prior art shown in DE 89 105 69.9 U1, the door is also operativewhen the holding screw 50 is removed because the bearing pin 7 can notbe pushed out of the upper bearing due to the securing screw 48.
